SAW-SET.

Application filed March 31, 1910.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Serial No. 552,622.

To all whom it may concern:

Be it known that I, ALEXANDER LINK, a citizen of the United States, anda resident of Phoenix, in the county of Maricopa and Territory ofArizona, have invented a new and Improved Saw-Set, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a saw set for setting theteeth of saws, regardless of the kind of saw or the number of teeth onthe saw to be set.

For the purpose mentioned use is made of a frame for engagement with thesaw, and provided with spaced heads mounted in the frame and adapted tomove toward and from the teeth of the saw, and means on the frame foradjusting the heads relatively to each other.

Reference is to be had to the accompany ing drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is apartially sectional side elevation of my invention, showing a sawclamped therein with one of the teeth of the saw being set; Fig. 2 is aplan view of my invention; Fig. 3 is a fragmentary side elevation,disclosing various features, parts being broken away to show theunderlying structure; Fig. -1- is a sectional view, taken on the line Hin Fig. 3, looking in the direction of the arrow, and Fig. 5 is asectional view taken on the line in Fig. 2 and looking in the directionof the arrow.

Referring to the various figures, I employ a frame 10, having adepending lug 11 at the forward end and provided with upwardly andoutwardly extending lips 12. Screwthreadedly mounted on the frame at therear end thereof is a screw 13, provided at one end with a handle 14,and having the other end of the rod in engagement with a follower 15,mounted to slide on guides 16 of the frame 10. For the purpose ofreducing frictional contact the follower has a circular groove 17therein, and the screw 13 has a circular lug 18 adapted to fit into thegroove 17, and suitable ball bearings 19 are interposed between the endsof the screw 13 and the follower 15, to permit the screw 13 to moreeasily turn in the follower 15. The forward end of the follower 15 isprovided with forwardly-extending lugs 20, on both sides of the follower15, and mounted in the said lugs 20 is a rod 21 on which are slidablymounted a number of heads 2. Mounted in the frame 10 are screws 23,provided with knurled h .tKlS 24c and encircled, intermediate the frame10 and the heads 24:, by springs 25, as will be readily seen byreference to Fig. 2. The other ends of the screws 23 serew-threadedlyengage the rear end of the follower 15, and tend to hold the follower 15against the end of the screw 13. The upper sides of the heads 22 areprovided with guideways 26, adapted to engage a guide 27, secured to theframe 10 by means of suitable screws 28, and the said guide 27 isprovided with depending tongues or auxiliary guides 29, adapted toengage the outermost heads 26. An adjustable screw 30 having a knurledhead 31 is mounted in the frame 10, and engages the auxiliary guides 29in engagementwith the outer heads 26. The screw 30 is provided with twooppositely-extending threads 32 and 32, with a space 33 intermediate thesaid threads and centrally disposed on the said screw." By means of thisconstruction, when the screw 30 is turned, the outer heads 26 will beadapted to move either toward or away from each other, as will be seenby referring to Fig. 4. On the under side of the frame 10 is slidablymounted a clamp 31, having secured thereto by a screw 35 a right-angledmember 36, in engagement with the under side of a head 37 mounted on thespaced portion of the screw 30. The clamp 31 is conveniently controlledby a screw 38, mounted in the frame 10 and provided with a knurled head39, for more easily operating the same, to move the clamp 34 forwardlyor rearwardly. As the head 37 is mounted in the spaced portion 33, whenthe screw 30 is operated the l1tl 37 will not move transversely of theframe 10, as do the heads 26, but the head 37 will remain stationary atall times with respect to the heads 26. A lug 41-0 is mounted on thescrew 38 and held in position by small outwardlyextending points 42,secured on the frame 10, the purpose of the said lug 40 being to enablethe screw 38 to be turned to move the clamp34: forwardly or rearwardly,as will be more fully referred to hereinafter. On the upper side of theframe 10, at the forward end and intermediate the lips 12, is an anvil43 extending transversely of the frame 10, as will be easily seen byreferring to Fig. 2. The anvil 13 has a downward1yextending portion 14:provided with a beveled edge 45, and the said downwardly-extendingportion 44 is adapted to slide in grooves ettS on both sides of theframe 10. A screw 4&7 engages the anvil 43, and is provided with a fixedwasher AIS, disposed underneath the anvil l3. By operating the screw at,the anvil 4:3 can be raised or lowered to any convenient height withrespect to the heads 26 and 37. The heads 22 and the center head 37 arepointed at their forward ends, so that when they are moved to engage theteeth of a saw, the points of [he said heads will bear directly on theexposed side of the teeth of the saw.

When it is desired to set a saw 49 with my device, the saw is secured tothe frame 10 by the clamp 34: holding the saw against the dependingportion 11 of the frame 10 and against the bevel of the anvil 6L3. Thesaw is so clamped in-the frame 10 that the point of the center heat 37will be directly opposite one of the teeth of the saw lf). The screw 30is then turned so that the outer heads 22 will each be opposite teeth onthe saw, as is the center head 37, and the positioning of the headsopposite the teeth of the saw is preferably arranged so that every othertooth will be in alinement with a head of the saw set. The handle l l isthen turned to the right, and the heads 22 and 37 are moved forwardly,as has been heretofore described, and engage the mentioned teeth, tobend the same outwardly against the anvil 43. After every other tooth ofthe saw has been set as described, the .saw is unclamped from the sawset, turned around and reclamped in the saw set, so that the teeth notpreviously set aline with the heads 22 and 37, and, the operation ofsetting the teeth is repeated as heretofore described.

It will be understood that any number of heads can be employed andoperated in the manner described,and it will be easily seen that onlyfor the purpose of disclosing the features of my device I employ a sawset with three heads.

It will also be understood that I do not limit myself to the preciseconstruct-ion shown, the scope of my invention being fully disclosed inthe appended claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A saw set, comprising a frame for engagement with a saw, spaced headsmounted in the frame to move toward and from the teeth of the saw, anadjusting screw on the said frame for moving the heads transversely ofthe frame and relatively to each other, a right-handed thread on thesaid screw and engaging one of the said heads, for moving the same inone direction, a lefthanded thread on the said screw, engaging one ofthe said heads, for moving the same in an opposite direction, andscrewthreaded means engaging the said heads, to operate the same to movetoward or from the teeth of the saw.

2. A saw set, comprising a frame for engagement with a saw, spaced headsmounted in the frame, to move toward and from the teeth of the saw withthe outer heads adapted to move transversely of the frame and the centerhead adapted to remain stationary with respect to the transverselymovable heads, means for moving the said outer heads transversely, meansfor moving the said heads toward and from the teeth of. the saw,'and ananvil mounted 011 the said frame and adapted to be adjusted.

3. A saw set comprising a frame, a guide thereon, auxiliary guidesmounted to move transversely on the said guide, heads mounted to move onthe auxiliary guides, means for moving the auxiliary guides transverselyof the frame, and means for moving the heads longitudinally of theframe.

l. A saw set comprising a frame, an ad justable anvil on the frame, aguide on the frame, auxiliary guides mounted to move transversely on theguide, heads mounted to move on the auxiliary guides, a screw foroperating the heads toward or from the anvil, and a screw for moving theguides transversely of the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
